When this bit is written to logic 0, the clock will start.

Then, choose either single mode or burst mode to input the data. The REST pin is also used to terminate either single-byte or burst mode data format. REST remains at high level. Then, choose either single mode or burst mode to input the data Data can be de- livered 1 byte at a time burst bytes For the most up-to-date information, please visit our web site at http: Pad Jt1381 Pad No.

Data can be de. Both input and output data starts with bit 0. When it is set as? Taipei Office 5F, No. The Write Protect bit cannot be written to in the burst datasneet.

The number of days in each month and leap years datasheey automatically adjusted. The clock halt bit must be set to logic 1 oscillator disabled. Data contained in the clock register is in binary coded decimal format.

In order to obtain the correct frequency, two additional datawheet capacities C1, C2 htt1381 needed. When D5 is logic 1, it is PM, otherwise it? This is to determine whether a read, write, or test cycle is operated and whether a single byte or burst mode transfer is to occur. The value of the capacity depends on how accurate the crystal is One is in single-byte mode ad the other is in multiple-byte mode. In order to minimize.

Holtek reserves the right to alter daatsheet products without prior notification. Additional SCLK cycles are ignored. Refer to the table shown below and follow the steps to write the data to the chip.

The value of the capacity depends on how accurate the crystal is. A Hz crystal is required to provide the correct timing. These bits control the operation of the oscillator and so data can be written to the register array.

The REST pin must be taken low again after the transfer operation is completed. All other trademarks are the property bt1381 their respective owners.

Data inputs are entered starting with bit 0. The data transfer is illustrated on the next page. Data outputs are read starting with bit 0. There are eight registers used to control the month data, etc.

Only three wires are required:. Only three wires are required: Data can be written into the designated register only if the Write Protect signal WP is set to logic 0. If used generally, unpredictable conditions may occur.
